WRENCH.

Specification of Letters Patent.

Patented March 3, 1908.

Application filed June 15, 1907. Serial No. 879,173"

type commonly styled monkey wrenches.

The invention has for its object to provide a quick acting wrenchwherein the use of screw threads and nuts is entirely eliminated foradjusting the movable jaw of the wrench.

Another object of this invention is to pro vide a simp e, inexpensiveand durable wrench, that can be easily and quickly adjusted, the wrenchbeing articularly designed for rotating nuts and similar objects havinflat surfaces.

Wit the above and other objects in view which will more readily appearas the invention is better understood, the same consists in the novelconstruction, combination and arrangement of parts to be presentlydescribed and then specifically pointed out in the appended claims.

Referring to the drawings formin a part of this specification, Figure 1is an e evation of a wrench illustrating the movable jaw thereof insection, Fig. 2 is a cross sectional view of a portion of the movablejaw taken on the line xa: of Fig. 1, Fig. 3 is a horizonjzal sectionaflilir iew of la wrench taken on the ine 'y'y o i 1, ig. 4 is aperspective view of the locking 'member of the wrench.

To put my invention into practice I construct my wrench of a shank 1having a fixed head or jaw 2. The shank upon its under edge is providedwith teeth 3, and while the shank can serve functionally as a handle, Idesire the privilege of placing the handle upon the shank if necessary.

Slidably mounted upon the shank 1 is a movable jaw 4, having straps 5embracing "the shank. The jaw 4 is provided near its upper end with alongitudinal] dis osed o ening 5 having the si e walls t ereo providedwith oppositely dis osed grooves to he opening 5 extends from one en ofthe jaw and is contracted at the other end, as at 7. Communicating withthe opening 5 is a vertically disposed opening 8 for a headed pin 9secured in a locking member 10 slidably mounted the opening 5. Thelocking member is provided upon its sides with ribs 11 adapted to fit inthe guide-ways 6 of the jaw 4. The forward end of the locking memberterminates in a tooth 12 adapted to extend from the contracted end 7 ofthe opening 5, while the rear end of the locking member 10 is bifurcatedas at 14 and formed with a shank or pin 15. Surrounding the pin or shank15 and within the opening 5 is a coil spring 16 confined within theopening under tension by a late 17 suitably secured to the outer end 0the jaw 4. The tension of the sprin 16 is adapted to maintain the tooth12 o the locking member in enga ement withthe teeth 3 of the shank 1, anwhen in such position, the tooth 12 is ada ted' to fit snugly in thecontracted end of t e opening 5. To release the locking member fromengagement with the shank 1, the headed pin 9 is manipulated, said pinbeing moved towards the outer end of the jaw 4, withdrawing the lockingmember from engagement with the shank 1 and permitting of the jaw 4being adjusted. The aw 4 can be quickly closed, as the beveled teeth 3of the shank permit of the locking member residing over the shank whilethe jaw is being closed, but prevents such jaw from being opened, unlessthe locking memher is manually moved out of engagement with the shank.

The wrench in its entiret is constructed of strong and durable meta andthe manner in which the operating parts of the wrench are housedprevents the wrench from being injured by ordinary use.

Such changes in the tion as are permissible by the appended claims maybe resorted to without departing from the spirit and scope of theinvention.

What I claim, and desire to secure by Letters Patent, is

A wrench comprisin a toothed shank having a fixed jaw, .the aw slidablymounted uponsaid shank, the upper portion of said slotted jaw providedwit an opening having the inner end thereof contracted, the side wallsof said opening formed with grooves to constitute guide ways, a lockingmember arranged in said opening and provided with lon itudinallyextending ribs seated in said guiiie ways, said member having itsforward end formed with a tooth adapted to extend through the contractedend of the opening details of construcand en age with the teeth of theshank and the shifting locking member and its other end 10.

said 100 g member having its other end biprojecting from the jaw.
